Причина отмены This test method covered the determination of methanol in propylene concentrates in the range of approximately 4 mg/kg to 40 mg/kg (parts-per-million by mass).

Formerly under the jurisdiction of Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants, this test method was withdrawn in December 2016. This standard is being withdrawn without replacement because of the availability of more reliable methods with better precision.
